Episode

This is a Livestream Q&A/Ask Us Anything for answering YOUR questions on YouTube. In this Q&A session we will answer your electrochemistry research questions LIVE, as well as any other questions related personal topics like careers, academia, industry, or life in general.

We have compiled a database of all questions asked in our Ask Us Anything About Electrochemistry Livestreams, tagged by the question subject and linked with time stamps to the place in that week's Livestream. If you are interested in obtaining a copy of this database (MS Excel file), please reach out via comments here or directly to us at [email protected].

Time stamps:
00:00 - Introduction
06:00 - Livestream starts
08:52 - For 2 and 3 electrode systems, how do the potential windows work?
22:36 - Do you think PEMFCs or SOFCs will have more research interest in the future?
28:38 - What's the role of iR compensation? How does uncompensated resistance affect the overpotential?
35:44 - I am interested in joining industry after completing my Ph.D. in supercapacitor research. How can I get an industry job?
45:05 - I think something is wrong with my potential window between 2 and 3 electrode setups.
52:36 - I want to ask a question about Rp (polarization resistance) of Al metal in alkaline solution. I recorded LSV at a scan rate of 1 mV/s, then making E vs. i plots over a potential range of ±10 mV from OCP, getting Rp as the slope. Is this scan rate too fast?
58:57 - How do you prepare an Ag/Ag+ non-aqueous reference electrode electrolyte, using dichloromethane and acetonitrile as solvents?
1:11:05 - What are limitations of the Nernst equation?
1:15:42 - For a pouch cell with liquid electrolyte, what material (e.g., Celgard 2500) should I use to contain the entire system to keep it from leaking?
1:25:46 - I am doing oxygen evolution (OER) on an electrocatalyst and getting a positive current before the onset potential of 1.23 V vs. RHE. How can I report this since it is a negative overpotential?
1:32:08 - Can you give an overview of the RDE and RRDE electrodes?
1:40:58 - In my EIS Nyquist plot, a part of the semicircle starts in the negative Zr region (x-axis). What does this mean?
1:48:30 - In CV, my material has a redox pair at 0.4 V, which only appears in a wide potential window. How is it possible to measure this redox process for EIS if I'm not able to apply the same potential window?
1:51:34 - Can you enlighten us on distribution of relaxation times (DRT) analysis for EIS plots?
1:55:50 - What should I look for in my EIS data to level up a publication discussion section when comparing different materials?
